鸭式气动布局导弹流场数值模拟

采用以N-S方程为主控方程的数值模拟方法,进行固定尾翼鸭式气动布局导弹的气动特性和流场数值模拟。系统介绍了文中所用的数值仿真方法。基于气动特性和流场分析研究了固定尾翼鸭式气动布局导弹的流场特性和气动特性,分析结果显示,在尾翼固定的状态下利用鸭舵的差动偏转进行滚转控制效率较低,基于流场仿真结果分析了鸭舵-尾翼间的滚转耦合机理。

Numerical Simulation of Flow Field for Canard-controlled Missile

To investigate the rolling control characteristics of canard-controlled missile with fixed-tail, a numerical simulation method based on N-S formulation was conducted. The simulation method and simulation results were introduced. The aero-dynamics characteristics analysis shows that the canard is not an efficient rolling control device for canard-controlled missile with fixed tail, and the flow field analysis shows coupling between canard and fixed-tail is obvious when canard difference deflecting.
